IMPROVEMENT IN COTTON-(EINS.

.To a'fZZ whom, it may concern:

Be it known that I, WILLIAM H. LIvINGs TON, of the city and State of New York, have invented, made, and applied to use a certain new anduseful Improvement in Cotton-Gins; and I do hereby declare the followingto be a full, clear, and exact description of the said invention,reference being had to the annexed drawings, making part of thisspecification, wherein- Figure l is a plan of my said improvement. Fig.2 is a side elevation, and Fig. 3 isa section, of said gin. v

Similar marks of reference denote the same parts. y

Cottongins have heretofore been constructed in which a roller coveredwith leather is employed, in connection with an adjustable breast-plateand vibrating stripper, to remove the cotton from the seeds,the samebeing adapted to the long-staple or sea-island cotton. The cotton hasbeen taken from this leather cylin der by different devices, among whichmay be named a swinging board that gives way with the weight of cotton,and then comes up against the cylinder to collect the next roll, asbefore.

rIhe nature of my said invention consists in combining with theginning-cylinder a detaining-board actuated by automatic mechanism,whereby the said board is moved away from the cylinder at regularintervals to allow the roll of cotton to drop. I also employ a series ofprojecting teeth, acting through or below the edge of the-detaining-board, which teeth gather the cotton and draw back at thetime ofthe roll or mass of cotton being delivered from the detainingboard or plate. l

In the drawings, a is the ginning-roller, set in a frame, b, andactuated by suitable power. 'Ihe ginning operation is performed by thewel1-known breast-plate and stripper found in this class of roller-gins,and does not require `further description or illustration, as myinvention only relates to taking the cotton off this leather-coveredginning-roller.

c c are arms or portions of the frame in which the journals of theboards orplates d and e are received, and t is a projection on d, takingagainst the end of one of the arms c, to prevent the lower edge of thisplate d swinging beyond a certain point as it comes up toward the saidroller a; and f is a weight on' d, to cause the lower edge of the plated to swing, when otherwise uiacted on, toward the roller a. The plate orboard e is provided with a row of pins or teeth, o,v at its lower edge,passing through holes near the lower edge of the plate d; or said pinsmight be below said lower edge of d, contiguous thereto, and this platee is weighted at 7c, to keep the lower edge in contact with the plate orboard d, so that the row of pins o will project through or beyond thelower edge of d and their points almost touch the cylinder a, At one endof e isa cam or projection, Z, acted on by a pin, n, on a wheel, m, thatis rotated by any suitable connection with the ginningcylinder. Vhenthis pin n comes around and takes the projection l, it swings the boardor plate e upon its journals, drawing the row OI' teeth or pins o back,so that their points are below the surface of the plate or board d, andhence withdrawn from the cot ton that had collected from theginning-cylinder a upon them and againstl d. The further movement of theplate or board e causes the board or plate d also to move, inconsequence of the board e near its upper edge taking against the backof d. This movement causes the lower edge of d to swing away from thecylinder a and drop the roll or mass of cotton, and the pin n passingoff the edge of p, the parts assume their former positions.

The lower edge of the board cl may have teeth projecting down betweenthe teeth of the row ofv teeth `or pins o upon e, so as to cause thedelivery ofthe cotton from such teeth when they are drawn back with theboard e.

It will be evident that the board d and teeth o may be placed at anydesired point higher up or lower down on the cylinder, so as to receivethe ginned cotton against its lower edge, and the projecting teeth orpins o act to detain the cotton, and when drawn back allow the whole ora portion of the accumulated cotton to drop, according to the length ofsuch teeth or pins, even if the board d were not employed to remove allthe cotton from such teeth or pins. p

Vhat I claim, and desire to secure by Letters Patent, is

l. Actuating the board or plate that receives the ginned cotton from theginningoylinder automatically and positively7 in order that it inwitness whereof I have hereunto set my may be drawn or swung away fromsaid oylsignature this 9th day of December, A. D. 1863. inder at regularintervals for ail'owingthe aecumulated cotton to pass away, as speed.WVM. IH.l LIVINGSTON.

2. A row of teeth or pins7 combined with the ginning-roller, when thesaid pins are ie- Vitnesses:
